Not a lot to report over the last week, I've been too busy to really work on the player but I did do a couple of things:

• Changed the address for the python client connecting to mpd from the loopback ipv4 address (127.0.0.1) to the host alias (localhost). This appears to have fixed a problem that when networked over USB the play button works because mpd is listening on ipv4, but when it's not it's onlly listening on ipv6 for reasons. No fucking idea, I'm going to blame systemd with no evidence and move on.
• Added a .mpdignore file containing a splat to the .git directory of my music collection so that it will stop picking up on the actual media files and keep using the nicely named symlinks instead.

Not sure that I'll have much time to work on it, but the next step is probably adding the OLED screen.
